GIS开发中可重用组件资源库的设计

Design of the Reuse Component Resources in the GIS Development

传统的GIS系统开发多采用结构化的设计思想,对于不同GIS信息系统的建设,需要重复去设计、开发相关模块,开发效率较低。将组件重用思想应用到GIS开发实践中,总结了组件、组件重用思想及组件开发流程,探讨了GIS开发中可重用接口的设计思路,包括:空间数据库连接和图层加载接口设计,数据查询和维护接口设计,空间分析接口设计。应用实践表明,基于可重用组件的GIS系统开发,可以高效、快速地开发出更稳定的应用系统,显著降低开发成本。

The traditional GIS application is mostly developed by adopting structured design thought,needs repetition of the design,develops related module,the efficiency of development is lower.So this paper introduced the reusable components to the GIS application development practice,summed up the component,component reuse thought,component development process,discussed the reuse interface design thoughts of GIS development,including:spatial database interoperation and layer loading interface design,data query and maintenance interface design,spatial analysis interface design.Practice shows that the GIS system development based on reusable components can be highly efficient and rapid developed a more stable system,the development costs can be significant reduced.
